SourceManager.h includes FileManager.h, which is expensive due to
dependencies on LLVM FS headers.
Remove dead BeforeThanCompare specialization.
Sink ASTContext::addComment to cpp file.
This reduces the time to compile a file that does nothing but include
ASTContext.h from ~3.4s to ~2.8s for me.
Saves these includes:
